[0018] Preferably, the cutter bars and the dredging blades of the dredging cutters are all detachable, to be maintained and replaced easily to save cost.
[0019] Preferably, a first long groove is formed in the support rod, a first threaded hole is formed in the same groove, and a fastening bolt passes through the first long groove to be fastened with the first threaded hole, so that the support rod is extended and contracted along the groove, and the connection is simple and convenient.

[0021] Preferably, a farthest dwell angle of the front non-equal dwell cams (identical with the rear non-equal dwell cams) is not less than 180°, to ensure full-process strong supporting. Since the cams rotate for one circle, that is, 360°, only when the farthest dwell angle of the non-equal dwell cam is not less than 180°, a sum of a nearest dwell angle, a lift angle, and a return angle is not less than 180°, and in this way, continuous strong supporting can be maintained in a full motion process. In other words, as shown in FIG. 14, at any moment, at least one curve of a front machine body supporting state curve SI and a rear machine body supporting state curve S2 is at a point Pl on a vertical coordinate, and the point Pl represents strong supporting.
Advantageous Effect [0022] Beneficial effects: compared with the prior art, the complete strong supporting single drive two-way crawling type pipeline cleaning robot provided by the present invention has the following advantages: 1. a power source and a set of mechanisms can realize complete strong supporting and two-way crawling in a vertical pipeline having a constant diameter or a diameter that has a very small change, and when the pipeline robot meets a specific obstacle and cannot walk forward, the robot can move backward to exit the pipeline, to enhance motor ability of the pipeline robot for dealing with a complicated pipeline environment; and 2. a robot body becomes more compact and portable, the cruising ability of the pipeline robot is greatly enhanced, and at the same time, full-process continuous traction can be maintained, and therefore, a vertical pipeline having a constant diameter or a diameter that has a very small change, that needs to maintain a continuous supporting force, can realize full-process strong supporting, and has actual engineering significance on comprehensive pipeline cleaning.

Since the farthest dwell angle of the non-equal dwell cam is 180°, during a full motion process, at least one of a front machine body and a rear machine body is in a strong supporting state. Therefore, when moving in a vertical pipeline, the front machine body and the rear machine body may not be destabilized due to insufficient support in a process of supporting a pipeline wall alternately. Furthermore, under a precondition that a size of a basic circle is constant and an allowed narrow force angle is not exceeded, since the farthest dwell angle of a non-equal dwell cam is required to be not less than 180° in the present invention, when the nearest dwell angle is constant, a radial variation range of the non-equal dwell cam relative to an equal dwell cam becomes small, and therefore, the present invention is only suitable to move in a pipeline having a diameter that has a small change or a constant diameter. Specifically, the present invention only requires that a value of a farthest dwell angle of a non-equal dwell cam is not less than 180°, and implementation of the present invention is not limited to the specific angle.
[0056] A specific implementation of the present invention is specifically described as follows.
[0057] A crawling process of a pipeline robot is shown in FIG. 13 and FIG. 14, and 15a-15e. According to a change of a position of a rotation angle of a rear non-equal dwell cam in FIG. 13, SI and S2 in FIG. 14 respectively represent radial supporting states of the front machine body and the rear machine body. To describe conveniently, a robot is divided into three parts, that is, a front machine body Bl (radial extension and contraction), a medium machine body B2 (axial extension and contraction), and a rear machine body B3 (radial extension and contraction). Meanwhile, extension and contraction states of each part are classified as three types according to an extension degree, that is, a full extension state, a medium state, and a full contraction state. A pipeline wall is not supported in a full radial extension state, is supported weakly in a medium radial state, and is supported strongly in a full radial extension state. A walking process of a pipeline robot is specifically described as follows.
[0058] Step 1: A crank 2-11 rotates by 0° in a clockwise direction. As shown in FIG. 15a, at
2018264305 08 Jan 2020 this time, a hinged hole on the crank 2-11 is at position 1. It can be known from FIG. 14 that, the front machine body Bl is in the full radial extension state, the medium machine body B2 is in a full axial contraction state, and the rear machine body B3 is a full radial extension state. [0059] Step 2: the crank 2-11 rotates by 90° in a clockwise direction. As shown in FIG. 15b, at this time, the hinged hole on the crank 2-11 is at position 2. It can be known from FIG. 14 that, the front machine body Bl is in the full radial contraction state, the medium machine body B2 is in a medium axial state, and the rear machine body B3 is in the full radial extension state.
[0060] Step 3: the crank 2-11 rotates by 180° in a clockwise direction. As shown in FIG. 15c, at this time, the hinged hole on the crank 2-11 is at position 3. It can be known from FIG. 14 that, the front machine body Bl is in the full radial extension state, the medium machine body B2 is in a full axial extension state, and the rear machine body B3 is a full radial extension state.
[0061] Step 4: the crank 2-11 rotates by 270° in a clockwise direction. As shown in FIG. 15d, at this time, the hinged hole on the crank 2-11 is at position 4. It can be known from FIG. 14 that, the front machine body Bl is in the full radial extension state, the medium machine body B2 is in the medium axial state, and the rear machine body B3 is a full radial contraction state.
[0062] Step 5: the crank 2-11 rotates by 360° in a clockwise direction. As shown in FIG. 15e, at this time, the hinged hole on the crank 2-11 returns to position 1. It can be known from FIG. 14 that, the front machine body Bl is in the full radial extension state, the medium machine body B2 is in a full axial contraction state, and the rear machine body B3 is a full radial extension state.
[0063] Through markings (A-F) in FIG. 15a to FIG. 15e, it can be clearly seen that, the pipeline robot crawls to the left along the pipeline and realizes continuous strong supporting crawling in a full process.
[0064] The present invention, through a combination of a connecting rod mechanism, gear transmission, and a non-equal dwell cam mechanism, that is, a power source and a set of mechanisms, realizes radial contraction and extension of a front machine body and a rear machine body of a robot, and extension and shortening of a spacing between the front machine body and the rear machine body, to realize full process strong supporting and two-way crawling in a vertical pipeline, and at the same time, realize pipeline cleaning during a walking process, and enhance stability and reliability of a pipeline cleaning operation.
2018264305 08 Jan 2020 [0065] Based on coordination of the non-equal dwell cam group, the present invention realizes continuous traction and full-process strong supporting in a process of alternate changes of supporting states of the front machine body and the rear machine body. Therefore, the present invention is not only suitable to cleaning of a non-horizontal pipeline (for example, a vertical pipe) having a diameter that has a very small change, but also suitable to a horizontal pipeline having a diameter that has a very small change, and has actual engineering significance on comprehensive pipeline cleaning.
[0066] Only preferred embodiments of the present invention are described as above. It should be indicated that, a person of ordinary skill in the art can make several improvements and modifications without departing from the principle of the present application, and the improvements and modifications fall in the protection scope of the present invention.
